H EATING STOVE O R FU RNAC E.

SPECIFICATION forming part of Letters Patent No. 700,874, dated May 27, 1902.

- Application filed December 10,1901. Serial No. 85,381. (No model.) i

heating stoves and furnaces; and the object of my invention is 'to cause the products of combustion to pass beneath the stove or furnace through horizontal flues and then through vertical flues before they reach the Stovepipe, thus providing a large heat-radiating surface and giving out a large amount of heat that would otherwise pass directly into the stovepipe or chimney. ject by the construction illustrated in the accompanying drawings, in which Figure 1 is a top plan view of a stove embodying my invention. Fig. 2 is a side elevation of the stove, partly broken away and in section. Fig. 3 is a bottom plan view. Fig. 4 is an enlarged perspective view of the damper. Fig. 5 is a section of the vertical flues, taken on line a b of Fig. 2.

1 designates the body of the stove, supported by legs 2, secured to a plate3, secured across the bottom of the stove. & designates the air-inlet tube, secured to the top 5. The top 5 comprises a stationary plate 5-and a smaller portion 5, hinged thereto, forminga door for the reception of the fuel.

Opening into the body of the stove at one end thereof is a tube 6, which turns downwardly and opens into a box 7. Connected to box 7 are a plurality of flues 8. More or fewer than three of these flues may be employed. These flues 8 lie under the stove and are connected at their opposite ends to a box 9 at the rear of the stove. Rising from box 9 and connected thereto are 6 (more or fewer) flues 10, the upper ends of which are connected to a damper-box 12, which opens into the rear of the stove, as shown in Fig. 2. In the top of this box is an opening 132for a stovepipe 14. A damper, comprising two plates 15 and 15, set at an acute angle with each other, is secured to a rotatable stem 16, extending across the box 12 and through the sides thereof and I attain said ob-' terminating in a handle 17. The boxes 7 and 9 are supported by legs 18. 19 designates a stay-bolt connecting the legs 2 to prevent them from spreading apart.

The operation of the flues 8 and 10 and of the damper 15 is as follows: When the damper 15 is in the position shown in Fig. 2, it cuts off the stovepipe 14 from the body of the stove and the products of combustion pass down through tube 6, back through flues 8, and up through flues 10 into the stovepipe; but if a direct draft is desired, as when starting the fire or putting fuel into the stove, the handle 17 is turned so as to drop the damper 15 back to the position shown in dotted lines in Fig. 2'." This opens communication between the upper part of the stove and the Stovepipe, so that the smoke will be drawn out without passing through the flues S and 10 or issuing into the room if the door 5 isopen.

The top of tube 6 is made horizontal, so that a hearth-plate of any preferred shape may be supported thereby, if desired.

While I have described the preferred form of my invention, certain details thereof may be modified without departing from the invention. For example, the tube 6 might be made round or elliptical in section instead of rectangular, and for the boxes 7 9 differentlyshaped couplings for the flues 8 and 10 might be substituted. Said boxes are one means of connecting the horizontal flues to the vertical flues and the tube'6.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination, with a stove or furnace body, of a flue thereunder, a tube connecting one end of said flue to the lower front portion of the body, a vertical line connected to the opposite end of said flue, a chamber communicating with the upper back portion of the body and with said vertical fiue, an opening in saidchamber for a Stovepipe, and a damper in said chamber, said damper being so movable as to cut off said chamber from the stove-body when in one position and to open communication therebetween when in a different position; substantially as described.

2. The combination, with a stove or f nrnace' body, of a plurality of lines thereunder, a tube connecting the front ends of said flues to the lower front portion of the body, a plurality of vertical lines connected at their lower ends to the rear ends of said flues, a

chamber communicating with the upper back lower portion of said body, a plurality of vertical flues connected at their lower ends to the rear ends of said fines, a chamber communicating with the upper back portion of the body and with said vertical fines, an opening in said chamber for a Stovepipe, and a damper in said chamber said damper being so movable as to cut off said chamber from the stove-body when in one position, and to open 7 communication therebetweenwhen in another position, substantially as described.

In testimony whereof I aflix my signature in the presence of two witnesses.

DAVID F. WINN.
